Here is a video of the first time my 2004 RX8 turned on in about 6 months. Still has the same problem; it doesn't stay on unless i keep the RPMs up.
you will notice my check engine light turns on @ 0:34
if you skip ahead you will see that when i let go of the gas @ 2:08 the car turns off
rx8 problems
my car wont start anymore. and when i pop the clutch, the engine sounds horrible.
RX-8 Rotary decarb part 1
Decided at 25,000 miles, it was time for a decarb. Used seafoam rather than Mazda's cleaner. I placed two tubes in the can of seafoam, and ran each line to a separate vacuum port, so I could do both rotors at the same time rather than separately. After sucking up all the seafoam, let it sit for a little over an hour. Then I put a cup of Idemitsu in the empty seafoam can, used the two tubes again, to help lube the rotary chambers during initial startup.
Afterwards, low end torque seems improved, and throttle response is way up, most notably when starting out from a stop. No bogging down, other than when I clutch poorly ;). Idle is PERFECT. While idling, there's no vibration from the engine whatsoever. Like new.
And as expected, the check engine light came on afterwards, and stayed on for about a day before going out.
Update 03.08.12: Some have questioned how well the Catalytic Converter has held up after the seafoam cleaning.. First off, 14,000 miles later, it appears to be fine. No power loss or other symptoms of a failed cat. However, that doesn't mean that the life of the cat hasn't been shortened. Looking back, I should have disconnected the cat before this procedure, and will do that in the future, and would advise anyone else with a cc and doing this procedure to do the same thing.
For those that have questioned whether or not I should have introduced seafoam into the engine at all: Mazda has a decarb procedure of their own, using a product similar to seafoam.
DIY Rx8 Seafoam Cleaning
MAKE SURE ANNOTATIONS ARE ON.
This is a DIY of me seafoaming my Rx8. This is being done on my 2004 with 98k miles. This is the second time I've cleaned my 8, the first being at 70k. I hope this is helpful! All the instructions are on the annotations. To make sure everyone's clear, you inject each port twice in order to relieve some of the strain from the starter. Should be roughly 4 oz per port, 8 oz total. You can pour the rest in the tank to help clean up your fuel injectors.
RX8 after deflooding
Plenty of smoke but it works! we connected the windscreen washer reservoir to the maintenance ports on the engline, gave it a couple of short squirts in each port, closed them up and kept the key turned for about 20s with the gas all the way down and then did it again with no pedals pressed.
car is totally stock.

The car worked perfectly after this i just felt the need to post this to demo that this amount of smoke isn't the end of the world!
Update - Sold in November 2012 for a BMW 335d...stay tuned!

RX8 Startups (Before and after new plugs, coils, battery, and eventually new engine)
RX8 Startups (Before and after new plugs, coils, battery, and eventually new engine)
My eight had a hard time starting so after changing out the plugs, coils, and battery I took it to the dealer for a look. Their diagnosis? "Use different gas".... don't take your car to Bankston Ford Mazda in Fort Worth. I took it to a local dealer (Hiley Mazda of Hurst) and they said I qualified for a new engine. It fixed the problem and then some.
RX8 Startup (before and after new plugs, coils, and battery)
Changing the plugs and coils helped a bit, but I took it to the dealer and ended up having to get the engine replaced. Had a year left on the warranty so it was free.
Here's a link to the new engine startups.

Test Drive 2007 Mazda RX-8 w/ Exhaust, and Full Tour
In this video I give a full in depth tour and test drive of a 2007 Mazda RX-8. I take viewers on a close look through the interior and exterior of this car while showing details, over viewing of features, and noting unique styling cues to the vehicle itself. I also show the engine and the details of it, start it up and see how it sounds under acceleration with a full test drive over various road scenarios you might encounter during daily driving. A thorough tour/review of this car designed to give others a greater overall appreciation of the vehicle.
